We need to write an article, 1500+ words, 6-8 paragraphs, each 150-250 characters? Wait Chinese characters count? It says "每段150-250字". Likely Chinese characters count. They want 150-250 Chinese characters per paragraph. So paragraph length 150-250 characters. 6-8 paragraphs. Must be at least 1500 characters total, can't be less than 1050 characters. So we need at least about 7 paragraphs of ~210 chars each ~1470 chars, plus maybe 8 paragraphs ~1680 chars. Need 1500+ characters. Let's produce 7 paragraphs of around 220-230 characters each, total ~1600 characters. Must not include title. Must begin with opening that echoes the title. Must end with conclusion referencing title. Use natural tone, avoid AI words. No bullet points. Must not use prohibited transition words like "、". Use logical flow without explicit transition words.
Need to ensure each paragraph 150-250 Chinese characters. Let's aim for ~210 characters each.
We need to count characters. Let's draft paragraphs.
Paragraph1: around 210 chars. It should echo title. Let's write:
"数据库连接池，多大才算最合适？其实没有放之四海而皆准的答案，关键在于业务特性、并发需求以及硬件资源。很多开发者在项目初期会随意设一个固定数字，后期却发现性能瓶颈或资源浪费。今天我们就围绕这个问题，聊聊如何在实际场景中给连接池配一个合适的尺度。"
Now count characters. Let's count manually:
"数据库连接池，多大才算最合适？其实没有放之四海而皆准的答案，关键在于业务特性、并发需求以及硬件资源。很多开发者在项目初期会随意设一个固定数字，后期却发现性能瓶颈或资源浪费。今天我们就围绕这个问题，聊聊如何在实际场景中给连接池配一个合适的尺度。"
Let's count: I'll approximate. Chinese characters count includes punctuation? Usually count characters including punctuation? Usually count characters excluding punctuation? But we can approximate length. Let's count characters ignoring punctuation maybe. Let's count manually:
数据库(3) 连接池(2) ，(punct) 多大才算最合适？(8?) Actually let's just approximate length. Might be around 100 characters. Need 150-250. So need longer.
We need each paragraph 150-250 characters. Let's produce paragraphs of ~200 characters.
I'll craft paragraphs with about 200 characters each.
Paragraph1: let's write longer.
"数据库连接池，多大才算最合适？这并不是一个可以直接套用经验值的问题，而是必须结合业务特性、并发负载以及底层硬件能力来动态调整的。很多项目在上线后会因为连接池设置过小而导致请求排队，甚至出现超时，又因为设置过大而消耗过多数据库资源，影响系统整体稳定性。下面我们从几个关键维度展开讨论。"
Now count characters (including Chinese characters and punctuation). Let's count roughly:
数据库连接池 (5) ， (punct) 多大才算最合适？ (8?) Actually "多大才算最合适？" is 7 characters plus punctuation maybe. Let's just approximate total length. Might be around 130-150. We need 150-250. Let's add more.
Add more sentences: "比如在电商大促期间，瞬时的订单处理请求可能会激增数千并发，若连接池容量不足，系统会迅速卡顿；而在普通查询场景，几百个连接已经足够，多余的只会浪费资源。"
Now combine. Let's rewrite paragraph with about 200 characters.
Paragraph1 final draft:
"数据库连接池，多大才算最合适？这并不是能直接套用固定数字的问题，而是需要结合业务特性、并发负载以及底层硬件能力来动态调整。比如在促销期间瞬时并发可能达到数千，连接池若设置不足就会导致请求排队甚至超时；而在普通查询场景几百个连接已足够，过大只会浪费资源。"
Now count characters: Let's count approximate characters:
数据库连接池 (5) ， (punct) 多大才算最合适？(8?) Actually "多大才算最合适？" is 7 Chinese characters plus punctuation maybe 8. Let's count whole sentence: "数据库连接池，多大才算最合适？这并不是能直接套用固定数字的问题，而是需要结合业务特性、并发负载以及底层硬件能力来动态调整。比如在促销期间瞬时并发可能达到数千，连接池若设置不足就会导致请求排队甚至超时；而在普通查询场景几百个连接已足够，过大只会浪费资源。"
Now count characters manually (including punctuation but each punctuation counts as a character). Let's count characters sequentially:
数(1) 据(2) 库(3) 连(4) 接(5) 池(6) ，(7) 多(8) 大(9) 才(10) 算(11) 最(12) 合(13) 适(14) ？(15) 这(16) 并(17) 不是(18) 能(19) 直接(20) 套(21) 用(22) 固(23) 定(24) 数(25) 字(26) 的(27) 问(28) 题(29) ，(30) 而(31) 是(32) 需(33) 要(34) 结(35) 合(36) 业(37) 务(38) 特(39) 性(40) 、(41) 并(42) 发(43) 负(44) 荷(45) 、(46) 最(47) 底(48) 层(49) 硬(50) 件(51) 能(52) 力(53) 来(54) 动(55) 态(56) 调(57) 整(58) 。(59) 例(60) 如(61) 在(62) 促(63) 销(64) 期(65) 间(66) 瞬(67) 时(68) 并(69) 发(70) 可(71) 能(72) 達(73) 到(74) 数(75) 千(76) ，(77) 连(78) 接(79) 池(80) 若(81) 设(82) 置(83) 不(84) 足(85) 就(86) 就(87) 会(88) 导(89) 致(90) 请(91) 求(92) 排(93) 队(94) 甚(95) 至(96) 超(97) 时(98) ；(99) 在(100) 普通(101) 查(102) 询(103) 场(104) 景(105) 几(106) 百(107) 个(108) 连(109) 接(110) 已(111) 足(112) 够(113) ，(114) 超(115) 大(116) 只(117) 会(118) 浪(119) 费(120) 资(121) 源(122) 。(123)
So about 123 characters, too short. Need 150-250. Need to add more content.
Add more sentences: "另外，连接池的大小还与数据库驱动的最大并发连接数、网络延迟以及事务持久时间相关，过度扩大只会消耗CPU和内存，甚至导致锁竞争加剧。"
Add this to paragraph. Let's append.
Now count added characters: "另外，连接池的大小还与数据库驱动的最大并发连接数、网络延迟以及事务持久时间相关，过度扩大只会消耗CPU和内存，甚至导致锁竞争加剧。"
Count: 其他 (2) 的(3) 等... Let's approximate length maybe 80 characters. So total maybe 200+. Let's rewrite paragraph with combined.
Paragraph1 final: combine earlier and added.
